function preforms much worse on CI

the entire process of getting through both the controller and the model functions is reportedly taking 0.0005 seconds(although the echo output appears after 2-4 seconds).

now in the worse case there will be 2 functions running in about the same time (0.001) and they two will iterate 9 times (0.009)that still does not explain how am i getting to 7 seconds (worse case).
i reckon that the problem can't be in the ajax for the entire loop (the one which runs 9 times) is made out of 5 rows, 3 of which are the ajax and another is the index incrementation.
